I I T2 aZZ, whom at may concern:

Be it known that I, MAX Leon WATERMAN, a citizen. oithe United. States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Sewing Machines, of which the following is a specitication, reference being had-therein to the accompanying drawings.

This invention relates to improvements-1n sewing machines employed more generally in the manufacture of boots, shoes, slippers,

&c., common to footwear and has for its bbject to provide a machine for stitching or for perforating and for stitching and perforatin at a single operation, a11l 't0 tl1lS end there is combined withone-formof commonly employed stitch-formingand clothfeeding mechanism means for perforating the fabric during or independent of the seam-formation.

In the accompanying drawings illustrating the invention, Figure 1 is a view in rear side elevation of the present constructlon,

the bracket-arm face-plate bein omitted. Fig. 2 is aplan View of Fig. 1. 3 is a view in front and elevation of Fig. 1. Fig. this an enlarged-view in rear side elevation of the front end portion of the arm-bracket. Fig. 5 is a plan view of the front end portion of the bed-plate with the slide plates in position to bring to view the loop-takers. Fig. 6 is an enlarged view, partly in full lines and partly in section, through the front end portion of the bracket-arm to better illustrate the means employed for actuating and discontinuing the action of the perforating punch. Fig. 7 is a view in perspective of the bracket-arm faceplate. Fig. 800mprises details, in perspective, of the perforat ing punch, lts carrier bracl et and a portion of the punch-bar. Fig. 9 1s a v1ew n perspective of the-gear-latch. Fig. 10 rapedse ts one form of product efi'ected b'y the" present construction.

ilhcpresent invention is herein shown and will be described as pplied to a idinger sewing machine, 'outit is to he understood that it is not limited in its applicability, its

mechanism being mounted and actuated indepcndently oi the sewihg machine proper except as it may be connected with the prime member of its actuating mechanism, and in describing the present invention only suclr' reference will be-qmade to the usual well known/ parts of the sewing machine as is deemed 'necessary for a properunderstanding of its application.

' Referring to the figures, i. representsthe machine base from which the standard 2 ea rrying the anwhracket in tof whic p igi. suitably ournaled the mam ordrivingshalt ,4. carrying at its forward end the slittlit' flange operatively connected, by the needle bar actuating link 6, with the needle-bar 7 provided with the needles, as 8,1thus transmitting from said main-shaft stitch-forming movements tosaid needles, which latter cooperate with the loop-takers, as 9, to form' stitches in a manner common to the art. 10 denotes a. feed-dog actuated through common means (notshown) to advance the material to the action of said needles, 11 the commonly.

employed hand or band-wheel and 12 the arm-bracket face-plate provided with the usual thread-tensions, as 13, thread-controller 14 and thread-checks, as 15, one only of which 2 is shown.

through commonly employed connections (not'shown), acts upon the'commonly emp oyed teed-dog actuating. mechanism to, at will, control the amplitude of feed move- ,-"ments of the feed-dog and 18 the needlethrca'd takemp common to thepresent ma- ,chine and actuated through a follower 19- tr ac'king a suitable-camgroove (not shown) formed in the shalt-flange 5.

Having-made such reference tothe elements comprising the feeding and stitchforming mechanism as is deemed su'flicicnt' to an understanding of the application of the invention there will now be described the latter. I

20 represents a bearing bracket secured by screws, as 21, passing through hollow lugs,

as 22, and threaded into the bracket-arm 3 and to said bearing bracket is secured by ably mounted on the shaft 26 to turn with the latter and onto said sleeve are suitably secured gear-members 32 and 33, the latter of greater diameter than-the former. 34 denotes a bearing stud suitably secured-in the bracket 35 secured by screws, as 36, to the bracket 20 and onto said stud is mounted to turn together the gear-members 37 and 38 of unlike diameters, thus at will, transmitting a greater or lesser speed to the gear 38, dependent upon whether the gear 33 is in mesh with the gear 38 or the gear 32 with that of gear 37, suchadjnstment of gearmembers being effected by adjusting the sleeve 31 to bring into mesh the gears 32 and 37 or as illustrated in the figures. The sleeve is slidably secured to rotate with the shaft 26 by the spline 39 and held against accidentalmovement in the direction of its length by the set-screw 40, the lug 25 and suitably secured collar 41 acting to limit the oppositely directed adjustments of said sleeve. When it is desired to change the combination of the gear drive just referred to, the operator, by manual manipulation of the band-wheel, brings into alinement the groove 42, in the hub 43 of the gear 37, and

' the groove M formed in the bracket 35 when the latch 45 is oscillated on its Pivot-screw 46 toa position toscat the blade 17 of saidlatch in the alined grooves 4244, thus locking the gears 37 and 38 against rotation while the sleeve 31 is shifted to bring into mesh the selected gear-member, after which the latch is returned to its normal position.

48 represents a punch actuating cam journaled on the main-shaft 4 and held against movement in the direction of the latter by the suitably secured block 49 and washer 50, at one side, and at its opposite side by the flanged collar 51 held by a suitable screw to turn the said main-shaft with its end of smallest diameter in contact with the gear- ,incmber 52 carried by the cam 48 in mesh with the gear-member 38 journaled on the stud 34, thus transmitting from said mainshaft,through the elements pointed out, rotary movements to said punch actuating cam, the driving and driven relationship of the gear-members for actuating the cam i8 is such that the latter is rotated in a direction opposite to that of said main-shaft.

53 represents a bracket suitably secured on the upper side of the bracket-arm and prospring 77.

yided with a tubular head 54 into which is ournaled a bearing stud 55 threaded into a bellcrank-lever, comprising the vertically and horizontally arranged arms 56 and 57 respectively, the free end 58 of the latter being seated in a circular bearing 59 formed in a block 60 movably mounted in a islet 61 formed in the punch carrying bar 62 and to the extreme upper end of the latter is'fixed a bracket-arm 63 which, at its free end, carries oppositely arranged downwardly projecting lugs, as 64, embracing the arm 57 to hold said punch carrying bar against movement about its longitudinal axis.

64: represents a stud-bolt journaled in the so I bearing stud 55 and having movements in the direction of its length in opposition to the resiliency of the spring 65 and to said studbolt is fixed, by nut 66 and-screw 67, the latter shown in dotted lines only, Fig. 6, a camfollower adj usting-yoke comprising the hori- 1 zont-al portion 68, handle 69 and the vertically arranged cam-follower adjusting-arm 70, the latter at its lower end having secured to it by nuts 71 a stud 72 carrying a camfollower 73 tracking a groove 7% in the punch actuating cam 48. 75 denotes the material-presser carrying-bar lifting collar and 76 the lever acting on said, cbllar to,-at will, effect vertical movements of the bar 75 in opposition, to the resiliency of the 48 represents a perforating punch adjnstahly secured by screws, as 79, to a punch holding bracket 80 which, in turn, is adjustahly secured by screw 81 to the lower end of the punch carrying bar 62, said punch being provided with a circular cutting edge 82 and with an opening 83 for the'passage of the cut-out portions of the matergial, said opening terminating in a pocket 84 from which latter said cut-out portions are freed from the perforating operation. 85 denotes t a throat or needle-plate provided with the feed-dog opening 86, needle openings, as 87, an anvil 88 secured by screw 89 against accidental movement and in position to receive the cutting edge of said punch. I

As previously )ointed out the fabric feeding and stitchorming mechanism is of usual construction and enters into the present organized machine as means having conjoint action with the inventive features for effecting the present product.

Having set forth the details in construction the following relative adjustments and eoiiperation of parts will be readily under stood.

Supposing the elements as oceu ymg their cooperative pos1t10ns,.as 1n the igures, for

effecting at a single operation the product: represented by Fig. 10, the two plies of ma -v terial 90 and 91 are advanced to the action of the needles and punch. b means common to the present sewing mac ine construction sufiicient to withdraw the cam-follower 73 ments by the cam 48 through the connections pointed out, but owing to the means employed for giving to said cam its rotary movements about the main-shaft 4: the perforations as 92 h: ve a wider spacing than the successive stitch formation, the relative arrangement of said spacing being capable of control by the adjustments previously pointed out.

When it is desired to discontinue the perforating operation and continue'the seamformation, the operator moves the cam-follower adjusting-yoke, in opposition to the resiliency of the spring 65, in the direction indicated by the arrow t,-Fig. 6, a distance out of engagement with the cam groove 7a of the cam 48. Through the-manipulation of the hand-lever 69 the yoke is rocked to a position to bring the stud-bolt 93 in line with the pin 95 secured in'the bracket 53,, when the resiliency of the spring 65 acts to seat the inner end of'the bolt 93 against the free 'end of the pin 95, thus disconnecting the seam mg and punch from its actuating mechanism and registering it out of; possible engagement with the material being acted on, said stud.- b'olt being secured by a nut 94 in-the arm 70 and passing freely. through an opening (not shown) in the arm 56 of the bellcranklever and when it is desired to discontinue the seam-formation and continue the per forating operation the operator removes the needles 8.

In Fig. 10 the product is shown as comprising twd plies, the perforations being effected in the upper ply theunder ply impressions, as 96, it being understood that through the vertical adjust ment of the punch relatively to its holder 80 perforations in single or multiple plies may be effected and in the latter any number less than the full number. Having thus set forth the nature of the in,- vention, what I claim herein is 1, In a machine of the character described,

the combination witha stitch-forming anda material feeding mechanism, of a perforating punch and means for actuating the latter to effect perforations in a numlier less than the full number-of plies of material acted on simultaneously with the being feeding operations.

2. Ina machine of the character described, the combination with a stitch-forming and a material feeding mechanism, of a perforating punch and means for actuating the latter to effect perforations in a number less .than the full number of pliesof material.

being acted on simultaneously with the seaming and feeding operations and means only which leaves in perforations and means independent of the latter means for spacing the successive stitch-formations.

4. In a machine of the character described, the combination with a stitch-forming and a material feeding mechanism, of a perforating punch and means for actuating the latter to effect perforations in the material being acted on simultaneously .with the seaming and feeding operations, andmeans for varying the spacings of the successive perforations with respect to given spacings of the successive stitch-formations. V

5. In a machine of the character described, the combination with stitch-forming and a material feeding mechanism, of aperforating punchand means for actuating the latter to effect perforations in the material being acted on simultaneously with the varying the spacings of the successive perforations with respect to given spacings of the successive stitch-formations and means. for locking the punch actuating means against accidental movement when efi'ecting the adjustments of said means for varying the amplitude of the spacings of said-successive perforations.

6. In a machine of the character described, the combination with a stitch-forming and a material feeding mechanism, of a perfoscanning and feeding operations, means for varying the spacings of the successive perforations and successive stitch-formations and means for locking the actuating mechanism'of the organized machine against ac .cidental movement when effecting th adseammg and feeding operations, means for justments of said means for varying the.

spacings of the successive perforations and successive stitch-formations.
